WallDamp System Calculator

For use in determining material quantities and costs for the ASC Walldamp System for sound conditioning and isolation we employ the WallDamp System Calculator. This system includes damping strips for studs, damping squares and strips for 2 layers of gypsum wallboard, and acoustic sealant. The system is designed to be installed upon new-construction framing and applies to one side per wall dimension entered. For treatment on both sides of a wall, enter the dimensions for each side as separate walls. To estimate how much WallDamp you will require, use the following tools:

For very small rooms (less than 80 square feet total area), accuracy decreases.
